My Wife and I (Karin & Joel) have 7 Guinea pigs. It all started when my wife and her friend went walking at a local park and found 3 guinia pigs, and when they spoke to the park worker he had 3 more. Thepark had found over 40 guinea pigs and he was calling animal rescue to pick the rest up. Well we kept 3, and my wife's friend kept the other 3. We took 1 from her and one of ours was pregnet. That is how we ended up with 7. The males have all been fixed. We have 2 C&C cages, one is 2X6 and the other is 2X5, I'll be adding a second story soon. We also have 13 bunnies, the whole side of the house is a rabbit run. I would say it's 5' X 40'. We have multiple house for them. Then we have 3 horse, kept at a stable near by and then 2 dogs and 3 cats, which own the house.
